Stem Split X2! YIKES!

It will be fine, now that it has dried out and has started healing itself, there is no point trying to stick them back together, which only works if done right after the injury occurring. Keep it dry and there will be no problems, if you cover it with tape/ties etc this can lead to moisture where it shouldn't be and then this can then lead to fungus and/or mould attacking. Best thing is to leave it and keep it dry. I have had plants with split stems 8 inches long and fall into two parts and just left them and they were fine. You can support the branches so the split does not get worse, but now that it has dried out, don't close it up, this is likely to cause more damage than just leaving it be. Hope this helps, Organoman.
